Z24O Posted August 10, 2006 Share Posted August 10, 2006 hi guys looking for opinions as to the suitability of this turbo for my 302 240Z..... forged 8.5:1 pistons,eagle rods,edelbrock performer heads,roller cam/rockers,have performer intake with injectors as well as tuneable engine management system but am contemplating going staight propane instead(have twin GRA gas carbies and twin B2 converters) really want to minimize lag and keep boost threshold low(revs) so wonder if the turbine A/R is too large(1.11),was considering using half the tangential inlet(ie 1.11 divided by 2) and running a 50mm external wastegate through a muffler to atmosphere(hoping to keep back pressure/heat down in the valve/heads)would love to be able to switch the wastegated gas thru the second half of the tangential housing at higher revs like a variable turbine....anyone have any thoughts on this?? compressor is supposed to be good for 55lbs/min or roughly 550hp which is about all i'd want to put a 302 block thru feel free to give your opinion and experience oh and forgot to mention i plan running an auto and 2800rpm stall converter GT3782 .58A/R TS04 compressor cover with 4" inlet 59mm inducer 82mm Major 1.11A/R T4 turbine housing 66.5mm exducer 72.5mm Major Full floating oil cooled CHRA 3" V-band outlet thanks guys paul western australia Quote Link to comment Share on other sites More sharing options...
Guest Killerbee Posted September 30, 2006 Share Posted September 30, 2006 The 55 lb/min is doable, however, if you run higher than 2.5 PR, compressor discharge temps will go through the roof. Liquid intercooling might be the way to go. It's hard to believe you can utilize 55 lb/min at that boost however. But it will run efficiently at all other reasonable boost levels. It is a proven design for the turbodiesels, it doesn't give up easily. Quote Link to comment Share on other sites More sharing options...

Z24O Posted October 1, 2006 Author Share Posted October 1, 2006 thanks for the input guys anyone hazard a guess at the spool up characteristics revs wise? how much quicker to boost would for example be a gt35r? Quote Link to comment Share on other sites More sharing options...
